3.84 TB SAS 12Gb/s enterprise SSD

The Dell Ultrastar DC SS530 WUSTR1538ASS200 is a 2.5-inch solid-state drive built for read-intensive workloads in servers and storage arrays. It delivers 3.84 TB of capacity over a 12Gb/s SAS interface with sustained sequential reads of 2150 MB/s and writes of 2120 MB/s. Dual-port connectivity and power-loss protection help maintain data integrity during unexpected outages.

Read-intensive arrays and hot-swap bays

This drive suits environments that prioritise consistent read throughput and hot-swappable maintenance, such as cloud storage tiers, backup repositories and analytics platforms. The 1 DWPD endurance rating and 2,500,000-hour MTBF support steady read-heavy duty cycles. Buyers who need higher write endurance or a different interface protocol should evaluate other drive classes.

1 DWPD endurance rating

The single specification that determines fit is the 1 drive-write-per-day endurance figure. It defines how much data can be written each day over the warranty period and directly limits suitability for write-heavy applications such as transactional databases or high-frequency logging. Match this number to your workload profile before purchasing.

Questions about this item

Will the 12Gb/s SAS interface on this Ultrastar DC SS530 work with my existing 6Gb/s SAS backplane?

Yes, the 12Gb/s SAS interface is backward compatible with 6Gb/s SAS controllers and backplanes, operating at the lower speed.

How can I verify the drive is performing at its rated 2150 MB/s read and 2120 MB/s write speeds after installation?

Run a sustained sequential benchmark tool such as fio or CrystalDiskMark against the raw device; results should approach 2150 MB/s read and 2120 MB/s write.

Does the 0P40594 part number include a 2.5in drive carrier or mounting screws, or must I order them separately?

The drive is supplied as a bare 2.5in unit; any carrier, caddy or screws required by your server chassis must be purchased separately.
